How can I edit JS from browser?

Suppose I get, on a page, this simple html/script :

<a id="hey" href="#">try</a>

var myvar=false;

$('#hey').click(function () {
    if(myvar)
    {
        alert("Well! You change it!");
    }
});

clicking on the link, I won't never get the alert show up! So, how can I edit JS (changing myvar=true;) on browser? I use Firebug... I need these details to test a security-side of my own application.
